True.  I should have said DTS-HD.  DTS-HD requires more bandwidth then 2 
channels @192K
can handle.  8 channels @192K provides enough bandwidth (768K) to handle 
the high
def audio formats such as DTS-HD.

They weren't necessary for the pass-through support, although they may 
be beneficial
for non-pass-through audio.
